The Total Brain Workout: 450 Puzzles to Sharpen Your Mind, Improve Your Memory & Keep Your Brain Fit

this book does what it says: it gives your brain a chance to solve problems that are not part of your everyday experience. Very enjoyable, and very enlightening!

I love math puzzles, alternative math education of every sort, and try to foist this material on my kids at every opportunity. This is the best puzzle book I've ever seen. And don't get fooled by the silly, generic cover that looks so much like any other book. The book organizes the puzzles into coherent types (logic, patterns, etc.), gives introductory strategies for solving, and gives a good number of practice problems of each sort. Most importantly, the problems are actually doable, tractable, reasonable. As a lifelong puzzler, I still think most similar books are either too difficult or have absurd and non-generalizable tricks to the solutions.
